Technically simplify is not a philosophy but a mantra or a manner in which one can approach a situation, a problem or a complex phenomenon. But since this is among the cornerstones of my life and attitude, I put it under the rubric of philosophy.
People who are comfortable within them and who are not bogged down by egoistic, intellectual burdens, I have seen, always write and communicate simply. So simply that even someone who does not understand anything about what they are talking about, can gather something from their communication. That of course also reflects on how well versed people are in their communications.
It is my attempt to work on the same principles- to simplify the complex for myself first and then if possible for others as well. We cannot solve any complex problems in the world if we look at complex phenomenon with complicated lenses. That is why lateral thinking is so vaunted.
